Washington, D.C. is set to face a stretch of dangerously hot weather starting this Saturday, with daytime temperatures rising steadily and peaking at 100°F on both Monday and Tuesday. With the heat index expected to feel like 104°F or more, the city is at risk for heat-related health concerns, especially for those spending time outdoors or without access to cooling.
Weekend Heat Rises in the Capital
According to the National Weather Service, Friday brings milder conditions with a high near 86°F. But by Saturday, temperatures climb to 93°F under mostly sunny skies. That’s just the start — Sunday is expected to hit 98°F with a heat index of 104°F, making it feel much hotter than it actually is. Tourists and locals near the National Mall and commuters along I-395 should be especially cautious during the afternoon.
Monday and Tuesday: Peak Heat in the District
The real danger comes early next week. Both Monday and Tuesday will see actual temperatures hitting 100°F, with high humidity pushing the heat index well into the triple digits. These conditions can lead to heat exhaustion or heat stroke if precautions aren’t taken.
The NWS strongly advises avoiding outdoor activities between noon and 5 p.m. when the sun is at its peak. People who must be outside should drink plenty of water, rest in the shade often, and wear light, breathable clothing.
Warm Nights Offer Little Relief
Even nighttime won’t bring much comfort, with overnight lows staying in the mid-to-upper 70s. This prevents the body from cooling down properly and increases the risk of overnight heat stress, particularly for those without air conditioning.
Smart Cooling Tips for Washington, D.C. Residents and Visitors
To stay safe during this extreme heat event, plan errands in the early morning or late evening. Consider using public transportation like the Metro instead of walking long distances. Cooling centers and indoor public spaces such as libraries and shopping centers can offer shelter from the heat.
Electric utility Pepco is urging customers to monitor energy usage as power demand may surge during the heat wave. Small steps like turning off lights, adjusting the thermostat slightly higher, and limiting the use of heat-generating appliances during peak hours can help.
Relief May Arrive Late Week
Although the heat will remain intense through Tuesday, there’s a chance of isolated thunderstorms by Thursday or Friday that could bring slight cooling. Until then, the District will remain in a high-risk heat pattern.
